    Scinario of arsenic pollution in groundwater: West Bengal

    西孟加拉地区地下水砷污染

    • 摘要: Abstract:Arsenic contamination in groundwater has taken a serious stage and it has entered the food chain now. Rice and other vegetables grown using arsenic contaminated groundwater are accumulating arsenic in levels greater than prescribed limit for health. Although several remedial solutions have been suggested, considering the socio-economic condition of the agrarian population, it is recommended to use surface water for irrigation. It may be difficult to switch over to this practice but there seems to be no other economical option suitable for this population. Over a period of years, the aquifer may provide safe drinking water and reduce the severity of the health condition presently experienced by the population.

       

      Abstract: 提要:目前,西孟加拉地区地下水砷污染问题日益严重并且已经波及到食物链中。由于吸收了砷污染地下水,谷物和蔬菜中砷含量日渐累积,超出了健康规定范围。尽管提出了若干补救方案,但是考虑到农业人口的社会经济状况,建议使用地表水灌溉方案。然而,实际中该方案仍然较难施行,且并无其他更经济有效的措施。若干年后,含水层可以减缓严酷的健康环境现状并为人们提供安全的饮用水。
